Finally figured out my "hill problem"! My wonderful fella drives me up (way up) a set of hills to the school where I walk the track as many times as the knees and hip will let me. I am up to 4 times round on this second day. Then I walk the 1/2 mile down the hills to home. With my sticks keeping the joints in alignment and keeping me from toppling, I think I am on my way. We asked the school, and they were delighted the community is using their facility.
